PET Oil Storage Cotton Strong Oil Locking Ability Microporous Polymer Cotton

• Chemical stability

• Inert strength: PET (polyethylene terephthalate) itself is a very stable polymer. It has excellent corrosion resistance to various components in essential oils, does not undergo chemical reactions with essential oils, and can ensure the taste and purity of essential oils.
• Odorless: Pure PET fiber itself has no odor and does not have the natural taste of plant fibers like some cotton materials (such as untreated organic cotton), thus avoiding cross contamination and ensuring the true restoration of essential oil flavor.

• Thermal stability

• High temperature resistance: The melting point of PET is usually above 250 °C, while the normal operating product temperature is much lower than this value (usually below 200 °C). This means that PET cotton will not melt, deform or sinter under normal working conditions, avoiding the production of harmful substances due to high-temperature decomposition.

• Oil conductivity and oil locking properties

• Quick oil guiding: PET cotton guides oil through capillary action between fibers. Its fiber structure can be designed and optimized to form uniform pores, thereby achieving fast and uniform oil conductivity, which can keep up with the evaporation rate of coils under high power.
• Good oil locking: While quickly guiding the oil, PET cotton can also effectively "lock" the essential oil to prevent leakage. Its oil locking ability is stronger than that of fluffy organic cotton, which is why it is widely used in pre oiled products.

• Structural strength and durability

• Not easy to collapse: PET fibers have good rigidity and can maintain their original fluffy structure and shape well during long-term immersion and use of essential oils, making them less prone to compaction or collapse. This ensures the long-lasting smoothness of the oil guide channel.
• Longer lifespan: Compared to organic cotton, PET cotton is more resistant to burning and sticking. In the case of sufficient essential oils, as long as they are not burned dry, their service life is usually longer and their performance deteriorates slower.

Application

Partial finished atomization core:

Many devices or finished atomization cores that can be filled with oil also use PET cotton as the oil storage medium inside. It integrates the oil guiding cotton and coil together, allowing users to replace them immediately after use, making it convenient and fast.

Advantage

• Extremely high consistency

As a standard product for industrial production, the fiber density, thickness, and length of PET cotton can be precisely controlled. This makes every atomization core produced with it have a highly consistent oil guiding effect and taste, which is incomparable to manual cotton filling and greatly facilitates large-scale production.

• High production efficiency and controllable cost

PET cotton can be made into rolls or embryos of specific shapes, which is very suitable for high-speed cutting and filling in automated production lines, greatly improving production efficiency and reducing production costs.

• Stable and reliable user experience

For the vast majority of users, using PET cotton products means' out of the box, stable and reliable. They don't need to worry about cotton filling skills, oil guiding speed, oil leakage, and other issues, providing a convenient and worry free user experience.

• Security is guaranteed

Its excellent chemical and thermal stability ensures that no harmful substances are produced under normal use, meeting the basic requirements for product safety.

Limitations analysis

Although PET cotton has significant advantages, there are also some limitations, which are mainly evident when compared to the organic cotton commonly used by RBA (Reconstructable Nebulizer) players:

• Subtle differences in flavor reproduction

In the eyes of RBA players who pursue the ultimate taste, high-quality organic cotton, due to its fluffiness and more natural fiber structure, may have a more "vivid" and "layered" restoration of essential oil flavors. The flavor reproduction of PET cotton is considered by some players to be somewhat "plain" or "dull".

• The instantaneous explosive power is slightly weaker

When dealing with instantaneous ultra-high power pulses, organic cotton may perform better than PET cotton and avoid dry burning due to its extremely fast instantaneous oil transmission speed.

• Non reusable

PET cotton is usually tightly integrated with the atomization core structure, and users cannot replace it themselves. For RBA players, organic cotton can be removed, cleaned, or replaced at any time, making it more playable and flexible.
